Parameters

The Parameters panel lists every fixture in your project, grouped by fixture type, and lets you adjust their parameter values. Each parameter corresponds to a DMX channel attribute (such as dimmer, color, or position) defined by the fixture's mode.

Groups

Fixtures appear under a header for their type, showing the type name and the number of fixtures of that type. Click the chevron next to a group to expand or collapse its parameters. Groups start collapsed; the expanded state persists per project.

When a group is expanded, every parameter the fixture mode exposes is shown as a single row. Dragging the bar on that row updates the value for every fixture in the group at once. When fixtures in the group disagree on a value, the row shows "Mixed".

Parameter rows

Each parameter row uses a draggable bar. Drag horizontally to change the value, click to type a precise number, or use the dropdown when the parameter has named ranges (such as gobo positions or strobe modes) to pick a named option.

The bar color reflects the parameter's GDTF FeatureGroup (intensity, color, position, beam, control, etc.) so you can identify the kind of attribute at a glance.

Per-fixture drill-down

Each parameter row has a chevron at its right edge. Click it to reveal one sub-row per fixture in the group, showing the fixture name, its starting DMX address, and an independent bar for that fixture alone. Drag a sub-row's bar to set just that fixture's value. The group-level bar above flips to "Mixed" when its fixtures' values diverge.

Drill-down state persists per project alongside group expansion.

Empty state

When the project has no fixtures with parameters, the panel shows "No fixtures with parameters". Add fixtures via the Fixtures panel and ensure they use a mode that defines parameters.
